The procedure for design and fabrication of highpower InGaAs strained-layer single-quantum-well lasers emit-0.98 pm has been demonstrated. single-quantum-well (SQW) laser. The lasers emit at 0.980 -+ 0.002 pm. They deliver over 100 mW CW optical power beam divergence of 15 -20". The maximum CW output power measured is 265 mW. The lasers have been successfully used as pump sources for an EDFA. High gain and high output power were obtained [21.
